Stormwater Utility Rate Structure

A rate structure was as an important step for Carrboro’s stormwater program in 2018, and updated in 2020. The rate structure is based on: Carrboro’s Town Code, which provides the legal structure; anticipated expenses for the utility; a GIS study of impervious surfaces in Carrboro; and experience from other North Carolina jurisdictions that have implemented utilities. Fees are calculated as a funciton of impervious surface relative to the “Equivalent Residential Unit” (ERU) of impervious surface. The rate structure is shown below. Additional information on changes in 2020 can be found here.
